A lubricant, such as oil or grease, is used to reduce friction between moving parts by creating a protective film that separates the surfaces and allows them to slide smoothly against each other. Lubricants help to minimize wear and heat generation in mechanical systems.
Yes, lubrication creates a protective barrier between moving parts to reduce friction and heat, preventing wear and damage. Proper lubrication ensures smooth operation and longevity of machinery and equipment.
